    I'm building a hard top and have glassed the tops and bottom. I vacuum bagged it and there are areas where the resin did not fully fill on the outside molded surface. This is an epoxy resin if that matters. What is a good filler that is easy to sand, and do I need to sand the surface prior to filling?
